ROTARY ENGINE,

Specification of Letters Patent.

Patented Jan. 17, 1911.

Application filed June 14,1910. Serial No. 566,801.

To all whom it may concern:

Be it known that I, EDWARD HAenR, a

citizen of the United States, residing at Bufialo, in the county of Erie and Stateof New York, have invented new and useful Improvements in Rotary Engines, of which the following is a specification.

The purpose of the invention is the provision of an engine of the rotary type de signed for the economical use of steam by expansive force, the engine comprising a plurality of turbines arranged to use the steam expansively in series.

- .The invention contemplates a novel construction and arrangement of the turbines,

' the elements entering into the construction thereof and the means whereby the steam is controlled and directed from one turbine to the other in successive order, the engine being reversible so that it may be driven either forwardly or backwardly with equal facility.

The invention consists of the novel features, details of construction and combination of parts, which hereinafter will be out in the appended claims.

Referrin to the drawings, forming a part of the application, Figure 1 is an elevation of a rotary engine or steam turbine embodying the invention. Fig. 2 is a vertical central longitudinal section of two of the turbines or elements of the series comprising the engine. Fig. 3 is a transverse section on the line w-w of Fig. 2. Fig. 4: isa' detail perspective view of the valve and operating means therefor.

Corresponding and like parts are referred to in the following description, and indi-. cated in all the views of the drawings, by the same reference characters.

The engine comprises a series of steam turbines A, A and A which are mounted in line and have a shaft 1 common to the series. It is to be understood that there may be any number of steam turbines or engine elements and that they increase 1n size'progressively from the receiving engine to they discharge engine. The receiving engine is the one having direct connection with the boiler or steam generator and re ceiving steam therefrom at boiler or high pressure. The. discharg ng engine 18 the last of the series and exhausts the spent steam either into the atmosphere or into a" hot well or other form of condensing chamber. The seyeral engine elements or turbines are in communication so that the steam exhausted from one engine is admitted into the next'engine to operatethe same by expansive force and so on throughout the series until finally discharged into the air or condenser. The shaft 1 is mounted in bearings 2, which consist of standards or uprights of any construction, the bearings being provided in number so that an engine is supported between each two of the bearings, as indicated most clearly in Fig. 1. A fly wheel or band pulley 3 is secured to one end of the shaft 1.

The several engine elements or turbines are of like formation except as to size, the latter increasing in progressive order from the receiving to the discharging turbine in the manner herein stated. Because of the similarity of construction of the several turbines a detailed description :of one will sufiice for a clear understanding of each. Each turbine or engine element comprises a cylinder, which is formed in two parts or sections 4 and 5. These sect-ions 4v and 5 have outer flanges which are apertured to receive bolts on other fastenings. By forming the cylinder in the manne stated the interior is readily accessible for any purpose. The section or part 5 is formed with a port i, whereas the section 4 has two ports 7 and 8, either one of which constitutes an inlet for the steam according to the direction of rotation of the engine, the port 6 forming an outlet or exhaust. A chest or valve casing 9 is secured to the section 4 and is provided with ports 10 and 11, which register respectively with the ports 7 and 8. The supply pipe 12 connects with the chest 9 of the turbine A. A rotary piston is arranged to operate in each of the cylinders and consists of a hub 13 and radial blades 14, the latter closely fitting the outer portion of the cylinder, which is made rounding. The rotary piston is keyed or otherwise secured to the shaft 1 so as to rotate therewith. Each of the radial blades 14 is provided with a packing to insure a steam-tight fit between the blades and thecylinder. The packing 15 is of substantially U-form and is-fitted in a groove formed in of the cylinder. Packing rings 29 are fitted, (into annular grooves formed in the sides of.

the end and sides of the blades. A spring 16' normally exerts an outward pressure upon the packing 15 to force the same 111 I contact with the inner wall of the cylinder,

said spring being located'm an opening formed centrally of each blade "14',v The packing 15 is of metal and its side members pnormally tend. to spring outward so as tov aintain a close lit against opposite sides the piston, said packing rings being pressed outward by means of springs 30 let into openings formed in the pistons. The packingf rings 29 maintain a"steam-tight joint between theside Walls of the cylinder and the sides of the' piston so as to prevent any escape of steam through the joint formed between the cylinder and the shaft 1.

" I It is observed that the inlet and the ex-.

haust ports are located at diametrically opw posite points'of thecyliiiders and for simplicity of construction and arrangement the cylinders have an alternate arrangement. in

/ successive order, so that the inlet of the first v turbine is, at the top and the exhaust at the bottom, and the inlet of thesecond turbine isat the bottom and'the-exhaust at the top and the inlet of the third turbine is at the top and the exhaust at the bottom and so on throughout the'series. This arrangement results in an alternate disposition of the,-

steam chests, as indicated most clearly in Fig. 1. The steam from the boiler, genera-.

tor or other source is supplied to the turbine A by means of the pipe 12 and the steam exupper s'eries of steam chestsland the con;

trolling valves operatedthereby for connection with said shaft. A shaft 21 is 'mounted in the heads of the lower chest or chests and has the valve or valves arranged to operate in the chest'or chests connected therewith. The two shafts 20-and' 21 are i connected for simultaneous operation at a like speed. While any means may be employed for connecting the two shafts 20 and 21 it is preferred to provide the shaft 20 with asprocket wheel 22 and the shaft 21 with a sprocket wheel 23, both sprocket wheels being of like diameter and connected w eel 25 is applied to one of the shafts, as 21, for turningthe same to fi'x the relative position of the valves. 9 has a valve 26, which is prov'idedwith a slot or opening 27 to receive a head 28 mm neans of a sprocket chain 24. A hand- Each of the chests vided upon the shaft. Thevalve 26 has it s face made rounding to conform to the curved 'wall of the chest 9, said valve having a shankportion in which the slot or opening 27 is; formed. The head 28 is of rectangue lar formation and is adapted to have play in the slot or opening 27, thereby admitting of the parts readily adapting themselves when placing them together and at the same time";

admitting of inserting or removing the shaft by an endwise movement, the head 28 slidin into or out of the slot or opening 27 as wi 1 be readily understood. By m'ovingfthe valves 26 into one position one .or both of the ports 10 or 11 may be closed, thereby shutting off the steam or admitting the same into either one of the ports according to the direction of rotation of the engine. If the valve is turned to close bothports 10 andll steam is cut ofi from the engine. By

turning the valve to admit steam into the port 10 only the'engine is driven to'the left or by turning the valve to admit steam into the port 11 only the engine is driven to the ri ht. It will thus be understood that the valve is used both in the capacity of a throt--- tle and for reversing the engine and for regulating the amount of steam to be supplied to the engine according to the 'load'. i

The series of valvesare so arranged and connected that by operating the hand wheel 25 all the valves have a like movementand cooperate to control the steam to the respective cylinders or turbinesn 1 From the foregoing description,- taken in connection with the accompanying draw-.

ings, the advantages of the construction and of the method of o eration will be readily apparent to those skilled in the art to" which I the invention appertains, and while I have described the principle of operation of the invention, together-with thedevice which I now consider to be the embodiment thereof, I desire to have it understood that the device shown is merely illustrative, and that such changes may be made when desired as. are within the scope of the claims appended hereto, T
